T a/Z whom t may] concern:

Be it known that LWILLIAM SCHEMENOUR, residing at Findlay, in the county of llancock and State of Ohio, have invented certain new and useful Improvements in Tag ons, of which the following is a specification, reference being had therein to the accompanyin g drawings.

rlhis invention relates to the running-gear Io of wagons, and especially such wagons as are intended to turn short curves.

The object of the invention is to improve the construction of this class of Wagons,so that much of the gear Inay be of wood, for

lightness, yet the wearing parts may be of metal and of such form as to be quickly and firmly connected; also, to produce a runninggear of this character which may be cramped with but little friction; also, to connect the 2o parts in a strong and durable manner at a moderate cost.

Figure l is a top plan of the front axle of a Wagon and immediate connections, according to my invention. Fig. 2 is a rear elevation, partly in section, of the front axle and connections, the wheels being omitted. Fig. 3

is abottom plan view of the axle and connections in cramped position. 4 Fig. 4 is a detail section of antifriction-wheel and connections to one of the short axles. Fig. 5 is a section, and Fig. 6 a side elevation, of cupped wearplates and bearing hereinafter described.

Fig. 7 is a section of another cupped wearplate and bearing. Figs. 8 and 9 are plan views of the wear-pieces, Fig. 7'-` The pivoted short axles A A are of wood,pro vided with usual Inetallic spindles or skeins A for the reception of the wheels. These short axles A are pivoted by strong bolts F bet-Ween the wooden truss-block D and the wooden bolster-bar B. The bolster C is secured to the bolster-bar and truss-block by king-bolt l, which passes through these parts, as well as through the tongue-carrier O. rlhe truss-block D has the integral central bridge 2 rising above the extensions 3 3. The bridge ends are secured to the bolster-bar by bolts 4f il.

The extensions 3 3 of the truss-block are each provided with a metallic wear-plate l-I, which is held to the wooden part of the truss-block by braces K passing through side lugs H" of the wear-plates and through the block and extending to hounds L, where the braces are attached. These wear-plates have cups in their upper surfaces and a circular face H5 55 projecting above the general level of the plate, the cup being' in the center thereof. The truss-block also has rigid metallic arc-plates E lirmly secured thereto in about the position shown.

The short axles A A have metallic wearpieces H on their lower surfaces, which wearpieces have ring-flanges H( surrounding the disk-faces H5 of the wear-plates, and having also bosses H3 to enter the cup in the wear- 65 plate. These wear-pieces H are connected to the short axles A by the pins The wear-pieces H H are thus interposed between the extensions of the truss-block and the short axles A when the parts are assembled and 7o serve as bearings and pivotal supports for the short axles and much strengthen the parts around the true pivots F.

The upper part of the short axle A is crowned, and on the crown is iixed a circular `7 5 Wear-plate G, having a central cup in its upper surface and a central boss G4, which extends into a countersink in the crown of the axle.

`The wear-piece G is held to the underside 8o of the bolster-bar by pins G2 and lugs GG. The position of the assembled parts isclearly shown in Fig. 2, and, as will be readily understood, the short axles A when so supported will be strongly connected both to the extensions of the truss-block and to the bolsterbar and at the same time will be pivoted so as to turn easily, and the bearing will be on metallic surfaces,'whiclr take the wear.

At the inner end of each of the short axles 9o there is a metallic socket or casting 8, having a pintle A2, on which the antifriction wheel or roll E is held by nut A3. This wheel or roll E runs on the arc-plate E, thus supporting the inner end of the short axle when in 9 5 straight or cramped` position and permitting an easy movement of the shortaxle on its pivot.

The short axles A each have an arm S firmly secured thereto, asby bolts 9, passing through I oo the axle and a flange on the arm, so that arms S are rigid with the short axles and project forward therefrom. One end of theI iiange may project into the axle-skein. The arms S preferably curve outward, as shown, so as to give a considerable sweep to the coupling-bar.

Coupling-bar R is connected by strong pivots 10 with the outer ends of each of the arms S and bybolt 11 to the tongue-carrier O. The tongue-carrier O extends through an opening P in the truss and rides under a brace-plate N behind the bolster-bar, the tongue-carrier being pivoted to the king-bolt 1. The tongue 12 is connected to the tongue-carrier in any suitable and usual manner7 as by straps 15 and bolt 16. A brace Q extends from the king-bolt below the truss-block to the bolt 11. The iit of the parts is such as to allow the tongue-support and connections to cramp the short axles, as shown in Fig. 3.

The reach H is connected to hounds L in suitable manner, and the hounds are connected to the truss-bar by bolts and braces, as indicated at 14, or in any other suitable manner.

From the description the operation of the device will be readily understood by those familiar with this art. The side movement of the tongue and support will cramp the short axles, the ends of the axles being supported by the antifriction-wheels running on in presence of two witnesses.

the arc-plates. The wear-plates not onlyhtake the wear, but act as braces and supports to the axles, both in straight and cramped po*- sition, and the tongue-support is braced and supported in all positions.

lVhat I claim is 1. In a wagon, the truss block havingy side extensions and a central bridge and the bolster bar having side extensions and rigidly connected to said bridge, the short axle pivoted( between the extensions of the bolster bar and bridge, arc plates rigid with the truss block and extending across the extensions thereof, and the short axle having bearings on said plates, all combined substantially as described.

2. In a wagon, the wooden truss block having a central truss and the bolster bar secured thereon, the metallic are plates secured to the truss block, the short axles pivoted between thc extensions of the truss block and the bolster bar, said axles having anti-friction wheels at their inner ends resting on the arc plates, all combined substantially as described.

3. In a wagon, the wooden truss block and bolster bar, the metallic are plates secured to the truss block, the short wooden axle having a metallic socket at its inner end, and having a pintle on said socket bearing an antifriction roll which travels on the arc plate7 and means for cramping said axles, all combined substantially as described.

In testimony whereof I affix my signature VILLIAM SCHEM EN OUR.
